Should check for for $form_state->get('uid') in alogin_ajax_callback

Problem/Motivation

With drupal 10, when the user login failed, it will trigger flood control. When the flood control is active, it did not set $form_state error, it directly return 403 response, hence to accomodate this, alogin.module should validate against $form_state->get('uid') along with $form_state->getErrors();

Steps to reproduce

Enable the flood control, set limit to 3 or 5, try to login using wrong password. Once the flood control triggered, you will have the user logged in

Proposed resolution

alogin.module alogin_ajax_callback should validate for presence of $form_state->get('uid') and $form_state->getErrors()

Remaining tasks

User interface changes

API changes

Data model changes
